Arginine amino acid, nano particles of zinc oxide, and stock density: Effect on growth performance, intestinal morphology, blood indices, and meat quality in broiler chickens.

ABSTRACT: The objective of this study was to investigate the effects of Nano Zinc Oxide (NZnO) supplements and arginine (Arg) on the growth performance, intestinal morphology, blood indices, and meat quality of Arian broiler chickens under high stocking density (HSD) conditions. A total of 672 one-day-old broiler chickens were assigned in a completely randomized design with a 2 × 2 × 2 factorial arrangement, included two levels of arginine (100 and 130 % of the Arian recommendation), two levels of nano zinc oxide (0 and 50 mg/kg), and two stocking densities (12 and 16 birds/m²), resulting in eight treatments with six replications. Results, revealed that HSD resulted in decreased daily body weight gain (DBWG) (P < 0.001), and daily feed intake (DFI) (P = 0.008) throughout the rearing perio
